I have the worst hair in the world. It is, what I call, wavy frizz grossness, and I think that is a pretty accurate description.I usually flat iron my hair, especially if I'm going out on a weekend. But my hair is ridiculous and usually starts frizzing up after about an hour or so depending on the humidity and such. I wish I could just bring a flat iron with me and use it in the bathroom...
OH WAIT, I CAN! Now, Sephora carries a "Professional Cordless Straightener" that is only a little more than 7 inches long! Perfect for throwing in your purse. It costs a steep $225--but it's well worth the price if I can have fun evenings out sans frizz.
